To all l214710112. 'it may concern.'

Be it known that I, ROBERT SULznn, engineer;4 a citizen of the Swiss Republic,re siding at 34 Obere lrlaldenstras'se, lVinterthur, Switzerland, have invented certain new and useful Improvements in Heating Apparatus; and I do hereby declare the folto be a full, clear, and exact description of the invention, such'as will enablewothers skilled in the art to which it appertaius to make and use the same.

This invention relates to heating apparatus employing the waste gases from an internal combustion engine.

It has frequently been suggested to utilize the waste gases of internal combustion engines for eatlng purposes, more particularly-the waste gases from engines of the Diesel type. Hitherto in suchapparatus lthe Waste gases Were brought into contact with coiledwrought iron tubes containing the Water to be heated, whichwas subsequently employed in various Ways, for instance to heat buildings on the hot water system. It has however been found that wrought iron tubes are corroded by the 1 waste gases, and for that reason cast iron tubes were used, but-difculty then arises in providing a suliciently large heating .area in the comparatively small space usually available.

According to this invention the cast iron' heat absorbing bodies of' the heating appa-` ratus are divided and connected in such a manner that a'large heating surface' can be arranged in a small space. To this end the heat exchange bodies, which are similar 4to those used as radiators in hotwater heating apparatus, are arranged, or 'connected' together in a manner so as to form a cham.

A construction of apparatus according to' this invention is illustrated in the accompanying drawing in which.:-

Figure 1 is a central vertical longitudinal section through the casing, the heating ele-A ments therein being shown in elevation;

' Fig. 2 is a vertical section on the line 2 2 combustion engine are admitted at b and ot' Fig. l; and'Fig. 3 is a horizontal section from which they escape at a. A series of -lar to the usual cast iron radiators, but having the connecting branches e of each memratented Jan. e, 15914. a

ber arranged diagonally opposite each other.

By connecting the individual members by' these branches, which may bev swiveled on each other, -a zig-zag, chain-like arrangement of the adjacent laterally overlapping members isobtained.' IIn that Way, it 1s poesible to extend the whole chain of members to a greater or less extent, and thus to makethev chain either-long'and narrow, or sh0rtand Wide, according to the dimensions. off Vater is admitted Vinto the space availablethe series of members atfandescapes from the same at g. i y

A's will be seen in Fig. 2'each link of the chain is preferably compound, comprising a set of individual members arranged side.

by side in spaced relation, the members of the several sets being interjacent or entering between each other, with transversecommunication between all the members at the Y alined swivel joints, whereby the current of water is divided into several 'streams thus improvingl the exchange of heat. Moreover, bythe staggered relation between theseveral sets, the members of each set being opposite the spaces of thel sets at opposite sides thereof and arranged transversely of the vpath of travel of the, gases through the casing, valuable results are secured.

In -t-he v arrangement described there is no need to have intermediate unionsor the like between the individual 'members'.or

i links and consequently the number of joints is reduced.

The heat exchange bodies are con cted by transverse pivots w, which also c nnect them to a supporting frame, which/T is shown as consisting of two side frames m), ai. The

latter have Iwheeled supports 0 at the bot-l 'A tom which enable the collection of bodies to be moved in. and out of the casing, the,

wise provided with handles. r' for moving them in and out. y I

Having now particularly described and passage of hot gases therethrough, arid holascertained the nature of my said invention and in what manner the same is to be per-1 within the casing'to form'inultiple paths tor the 'liquid and pivotally connected together by connectionsiransverse to the sets so as to constitute a chain for the purpose set forth.

A heating apparatus comprising a casing having an inletand an outlet 'for ,the

low elongated liquid-circulating bodies in the casing connected-in adjustable tort-rions series by transverse swivel communications at their' ends.

3. A heating apparatus comprising a casing having an inlet and an outlet for the passage of hot gases therethrough, and a series o'fhollow elongated liquid-circulating bodies in the casing, the several bodies being disposed transversely of the path ot travel of the gases andv the series being eX- tended in the direction of such travel, the said bodies having swivel communicating connections at their ends affording a tortuons passage for the liquid and rendering said series adjustable as to length and width.

4. In a heatexchange apparatus, a plu rality of sets of hollow elongated heat-exchange bodies, each set consisting of bodies arranged side by side in spaced relation, the ends of the bodies of successive sets being interjacent each other and interconnected crosswise of thesets by swivel communica tions. y

5. In a heating apparatus, the combination with a casing adaptedto have hot gases passed therethrough, of a series of laterally overlapping hollow oblong bodies therein connected alternately at their opposite ends by transverse swivel communications within said casing laliiording a tortuous liquid passage and permitting adjustment of the di-v mensions of the series.

ln a heat-exchange apparatus, the conn bination of a plurality of sets ot hollow oblong heat-exchange bodies, each set consisting ot bodies arranged side by side in spaced relation, the bodies off the several sets later`- ally overlapping between each otherV in stag Hto have hot gases geredv relation and being connected at the ends by swivel communications the axes of which are transverse to the sets.

7. ln a heating apparatus, the combinay tion of a series of laterally overlapping oblong hollow bodies, connected alternately at opposite ends by lateral swivel. communications .arranged` diagonally in the individual bodies.

8. The combination with a casing adapted I assedtherethrough, of ay plurality of set-s o laterally overlapping oblong hollow liquid-circulating bodies therein connected at their ends bytransverse swivel communications.

9. A heating apparatus comprising a cas ing adapted to have hot gases passed therethrough, and oblong hollow liquid-circulating bodies therein arranged in staggered sets the members of which enter between each other with integral lateral branches affording transverse intercommunication between the bodies of interjacent sets.

10. A heating apparatus, comprising a casing having an inlet and an outlet for the passage of hot gases therethrough, and elongated hollow liquidbirculating bodies therein arranged in sets, the bodies oi, suc-- cessive sets entering between each other and the ends ofthe bodies of one set .being dif rcctly connected to the interjacent bodies of the next setby communications disposed transversely of the sets.V j y ll. In a heat exchange apparatus, a series of hollow oblong circulating bodies laterally overlapping each other and having alternating lateral communicating connections at their ends, said connections being diagonally related in the individual bodies.

l2. Circulating means for heat-exchange apparatus, comprising a plurality of sets of hollow elongated heat-exchange bodies interleaving one with another, and connections arranged alternately at opposite ends of the and establishing' communication transversely throughout the members' of each set and between the members of interjacentI sets, whereby a plurality of crossconnectcd tortuous passages are provided.
